The Difference between a Warm Standby and Cold Standby Line Card
A warm standby is a line card that has been pre-configured with the same software and configuration as an active line card. Because the configuration is pre-loaded, a line card acting as a warm standby for an active line card provides the fastest recovery time available. However, a line card can serve as a warm standby for only one active line card.

A cold standby is not pre-loaded with the same configuration as the active line card. Since the configuration must be downloaded from the NMS server to the line card before the standby can become operational, a line card acting as a cold standby for an active line card takes significantly longer to take over for a failed active line card. However, a line card can serve as a cold standby for multiple active line cards.
